Code Description Problem/Solution
0401 CD-ROM drive not
responding
POST has detected the CD-ROM drive is not responding, but is
configured in the Setup Utility.
To correct this:
1. If the CD-ROM drive has just been removed, press [F4] to
automatically validate the change.
2. Verify all data cables and power cords are firmly connected.
3. If the cable is damaged, connect the hard disk drive to
another IDE cable, if available. The Setup Utility and the 32-
bit disk access driver may need to be modified accordingly.
4. If the problem persists, your CD-ROM drive may need to be
replaced. Contact your service representative to replace your
Netserver.
0500 Hard Disk (primary)

(This does not apply
to LP 2000r)
POST has detected a general failure on the integrated (primary)
hard disk controller.
To correct this:
1. Restart your HP Netserver.
2. If the error persists, your system board may need to be
replaced. Contact your service representative to replace your
Netserver.

disk drive to the other cable to operate with the secondary
controller. Verify the secondary IDE controller is enabled in

channel functionality. Contact your service representative to
replace your Netserver.

device may be defective. Contact your service representative
to replace your Netserver.
